This invention relates to a harrow attachment for plows, and has for one of its objects to provide a novel and simple attachment of this character which shall embody a frame carrying rows of teeth, and a bracket for supporting the frame from a plow in such position with respect to'the moldboard of the plow as to enable the teeth to work the soil as it is turned over.

The invention has for a furtherobjectto provide a harrow attachment of the character stated wherein one row of the teeth shall be arranged in advance of the other, wherein the rows of teeth shall extend transversely of the turned over soil, and wherein the teeth of the rear row shall be positioned laterally beyond the teeth of the front row, to the end that the turned over soil may be thoroughly worked.

The invention has for a further object to provide a harrow attachment of the character stated wherein the bracket shall be adapted to be secured to a plow of any suitable type without forming bolt receiving openings in 7 any part of the plow, and wherein the bracket shall be adapted to be secured to the plow in a manner to permit the teeth tobe adjusted vertically so that they may be set to penetrate turned over soil to the desired or required extent. a

The invention is hereinafter more fully described and claimed, and illustrated inthe accompanying drawings, wherein i+ Figure 1 is a view in side elevation illusltrating the harrow attachment applied to a plow. a

Thei'harrow attachment comprises aframe ly aifrontrowof"teeth 2 and a'vrear row-of teethx3. The frame 1 is of-elongated rec tangnlarformationin rplan and comprises a front angle bar 4,:aJrear angleibar Sand end 60 bars 6.

i When it is inapplied; positi-on,'=the' harrow I H attachment is locatedclosetto tlie rearend of the moldboard and extends laterally outward therefrom. The harrowz'attachment. is Socuredlto :andasupported :Erom'the beam-i12iand theanoldboard 13- ofvthe plow :by abracket 14 whichcomprises right'angularly related arms 15rand 16. The bracket :arm 15 extends from the-beam- '12: to the moldboard 13, and base .forwardlytdirected inner end portion, 17. and a rearwardlyqdirected outer end portio n18,-; Theybpadketapm portion lZis secured ,to tha beam 12 by a bolt 19 which secures the moldboard brace 20 to the beam. The bracket arm 16 is secured to the moldboard 13 by a bolt 21 which secures the brace to the moldboard. The frame 1 is secured to the bracket arm extension 18 by one of the bolts 7 and the bolt 9. The bracket 14 inclines upwardly, outwardly and rearwardly from its point ofconnection with the beam 12 to a point above and rearwardly of the rear end of the moldboard 13,

and its angular rear end portion is located in a plane parallel to that of the beam so as to arrange. the frame 1 and its teeth 2 and ,3 transversely of the turned over soil. The bracket arm 16 extends upwardly from its point of connection with the nioldboard 1-3, i

and is provided at its upper end portion with a vertical slot 22. The bracket arm'15 is secured to the bracket arm 16 by a-bolt 23 carried by the bracket arm 15 and passing through the slot 22.0f-the bracket arm 16.

The bracket arm 15 has a pivotal connection with the beam 12 so as to permit it to be adjusted to effect the raising or lowering of the harrow attachment and thus enable the har row attachment to be supported from the ing of the so'il.. The harrow attachment is plow with its teeth 2 and 3 at the required elevation.

The provision of the bracket arm 16 with the vertical slot 22. permits the adjustment of the bracket arm 15, and the bracket arm 15 is supported in its adjusted position from the bracket arm 16 by the bolt 23.-

In view of the manneriin which it is mount-- edupon the plow with respect to the moldboard'thereof, the attachment will break up the soil as it is turned by the plow, thus enabling the simultaneous plowing and harrowstrong and durable, may be manufactured at low cost, may be readily applied to a plow, and may be readily adjusted to set its teeth for penetration to the desired extent into the soil. turned by the plow. While the barrow attachment is shown as applied to a one-way plow, it is, to be understoodIthat it maybe:

applied to two-way-plows, gang plows and the like. While I have described the principle of the invention, together with the structure which I now consider the preferred embodiment thereof, it is to be understood that the structure shown is merely illustrative and'that such'changes may be made, when desired, as fall within the scope of the invention as claimed. a i What is claimed is r I A harrow attachment for a plowcomprising a bracket arm adapted to be pivoted to a plowbeam, a second bracket arm adapte'd'to be fixed-to the plow andp'rovided with a vertical slot, said first bracket arm crossing signature.
